HERBERT E. KEELER, OF NEW YORK, N. Y., ASSIGNOR TO CURTAIN SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

CURTAIN-FIXTURE.

To all whom it may concern:

Be it known that I, HERBERT E. KEELER, a citizen of the United States, and resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Curtain-Fixtures, of which the following is a specification, taken in connection with the accompanying drawings, which form a art of the same.

This invention re ates to curtain fixtures such. as are especially adapted for use in railway cars to allow the ready adjustment of the car curtains and to hold them securely in adjusted position.

In the accompanying drawings in which the same reference numeral refers to similar parts in the several figures, Figure 1 is an elevation partly in section showing an embodiment of this invention ap lied to a cur- Fig. 2 is an enlarged d tail sectional view showing one form of shoe. Fig. 3 is a transverse section through the same. Figs. 4, 5, 6, 7, 8 and 9 are sectional views similar to Fig. 2 showing other forms of shoes.

In the embodiment of this invention shown in the drawings, the curtain 34 is indicated as being attached at its upper end to the constantly acting spring roller 35. Suitable guideways of any desired form are rovided on either side of the curtain and t ese guideways may take the grooved form indicated. Shoes are carried by the curtain and cooperate with these guideways, 36, and for this purpose the curtain tube 40 may be secured near the bottom of the curtain in' a suitable ocket or otherwise. The shoes are indicated as formed with suitable plungers 30 which fit within the ends of the tube so as to be guided in their movement and each plunger is preferably held in the tube by a suitable screw or pin 31 engaging the plunger and having its head operating in a suitable slot in the tube. Each shoe is preferably ressed into cooperation with the guideway by a suitable spring 32 which as indicated engages a stop 33 in the tube and operates against the end of the plunger. The shoes are preferably provided with separated gulding members to engage the guideways and these guiding members preferably com rise suitable rotating guiding members w ich may be in the form of cylindrical rolls whose peripheries engage the guideways. One or more of these rotating guiding members in each shoe may be formed with a suitable locking clutch operating between the guiding Patented June 1, 1909.

member and the pin on which it is mounted so as to lock the guiding member against rotation in one direction. Any desired form of intermittently locking clutch may be employed for this purpose, the rotating member eing locked so that under the spring pressure used its rotation in one direction by engagement with the guideway is practically prevented. If only one intermittently looking clutched roll is employed in each shoe, this locking guiding member is preferably mounted below the other point of contact of the shoe with the guideway and in this case the intermittently locking clutch between the roll and the pin is preferably arranged to lock this roll against rotation by contact with the guideway when the shoe moves upward, but to allow the guiding member to rotate when the shoe moves downward, so that the curtain may be readily lowered but is prevented from being raised by the spring roller. If another intermittently locking guiding member is employed in the shoe above the other the intermittently lockin clutch may be arranged to look this secon guiding member against rotation by the guidewa when the shoe moves downward, but to al W it to be rotated by'the guideway upon the upward movement of the shoe.

The shoe may be provided with the roll 2 mounted upon the pm 7 below the center of the shoe. This pin is preferably rigidly secured in the shoe and may be riveted to the sides of the same, if desired, as indicated in Fig. 3. i A suitable annular roove is formed in the pin and a simi ar coacting groove is formed in the roll as indicated in F i s. 2 and 3 and the clutch spring 4 preferably having the curved contour indicated is secured at its inner end to the pin and lies when in operative position in the coacting grooves described. The end of this light spring engages the roll as soon as the roll begins to rotate in the direction indicated by the arrow in Fig. 2 and locks the roll against rotation in this direction. It is, of course, understood that these arts may be readily assembled by forcing tlie clutch spring into the recess 5 in the pin and thereupon inserting the pin and s ring into the roll after which the pin can e readily secured to the shoe, as indicated. The treads of the rotating guidingmembers used in this fixture may be formed of suitable material to roperly cooperate with the guideway and should be formed of such material as to give the proper V gripping action under the spring pressure 1 used and if desired may be suitably roughened or corrugated for this purpose. If desired, a similar intermittently locking clutched roll 2 may be mounted at the upper end of the shoe 1 as is indicated in Fig. 2, the clutch spring 4 being so mounted. in the pin 7 as to engage the groove in the roll and lock this roll 2 against rotation in the direction indicated by the arrow; so that this upper clutched roll is locked against rotation by the guideway when the shoe is moved downward, but rotates under the influence of the guideway when the shoe moves upward. If desired, however, a guiding member of any desired form may be used in connection with an intermittently locking clutched rotating guiding member in the shoe and this cooperating guiding member may, if desired, be a rotating guiding member, such as indicated in Fig. 4, in which the guide roll 6 may be mounted to rotate about a pin 3 in the shoe. The lower roll 2 is constructed and mounted as has been described in connection with Fig. 2 except that its tread is indicated as roughened or corrugated. This may, of course, be done in any case where necessary to give a greater holding action between the roll tread and the guideway. It is, of course, understood, however, that this cooperating guiding member may be non-rotary, if desired, and this may be accomplished in some cases by rigidly securing the guiding member 6 to the pin 3 by using a drive fit, for instance, or by tightly riveting the parts together so as to prevent its rotation.

Any other desired form of intermittently acting clutch may be used between the locking guiding member and its pin. Fig. 5 indicates the roll 11 mounted upon the pin 8 fixed in the shoe, this roll being provided with a suitable aperture 37 in which the pivoted clutch 9 is mounted so that its free end engages the pin 8. A suitable light spring 10 is preferably employed to hold the pivoted clutch in operative engagement with the pin, the proportion of these arts being such that the clutch locks the roll against rotation in the direction indicated by the arrow by the engagement of the guideway with the roll, that is, when the shoe is moved upward. A suitable cooperating guiding member may be mounted in the shoe preferably separated from the clutched guiding member described and this guiding member may be the roll 6 mounted to rotate about the pin 3. A suitable clutch block may be mounted in the rotary guiding member, if desired.

Fig. 6 shows the rotating guiding member 12 as mounted upon the pin 13 which is rovided with the notches 39. The clutch b ock 14 is formed to engage these notches and is mounted within a suitable aperture in the guiding member, the outer end of the aperture being closed by the plug 16 which confines the light spring 1.5 operating to hold the clutch block in engagement with the pin. This arrangement, as is indicated, locks the rotating guiding member against rotation when the shoe is moved upward.

A suitable spring clutch may be used instead of the clutch block indicated. Fig. 7 showing the clutched roll 17 mounted upon the pin 18 which is formed with the notches 38 and the spring clutch 20 is adapted to engage these notches, the spring being mounted in an aperture 19 in the roll.

A suitable rotary clutch member may be used, if desired, and Fig. 8 indicates the ball 23 mounted in a suitable hole in the guide roll 21 which rotates about the pin 22 tixed in the shoe 1. The plug 25 closes the outer end ol the hole in which the ball is mounted and a suitable light spring 24 normally presses the ball into engagement with the pin so that the roll is locked against rotation in the direction indicated by the arrow. the angle of the hole being such. as to give the proper locking action.

A number of rotary clutch members may be employed in the rotating guiding member. if desired, and Fig. 9 indicates a number of apertures 29 formed in the rotating guiding member 26 in which suitable balls or rolls 28 may be mounted to cooperate with the pin 27 upon which the guidii'ig member 26 rotates. The apertures are formed oi arving depth as indicated, so that the balls or rolls are wedged against the pin when the rotating guiding member tends to rotate in the direetion indicated by the arrow and thus lock this guiding member against rotation when the shoe moves upward. The clutched guiding member may, however, be rotated in the other direction by engagement with the guideway.

It is, of course, understood that many changes may be made by those familiar with this art in the form, proportion and number of parts of this device. I urthermore, parts of the same may be employed wi thout departing from the spirit of this invention or losing the advantages of the same. I do not, therefore, desire to be limited to the details of the dis closure which has been made in this case, but
